T/C Valve cover identification

PostPost by: s4elan » Sat Sep 04, 2010 3:46 am

Does anyone recognize this valve cover? It has a cast in boss for fuel injection.

It looks a lot like the Novamotor cover, except that in that one the space between the cams (ie over the plugs) is also covered, with similar ribbing. I don't know if there's any connection.

Sorry, no identification tips but I think it could be someone's own solution to cure leaky Cam Covers.
Those longitudinal Ribs together with added stiffness across the clamping Nuts will have increased the overall stiffness of that Cover & most interestingly the use of additional longer Studs & Nut locations on all the Cam Bearing locations will also help to spread the load more evenly across the Cover Gasket.
Even the use of Capped nuts (as shown) will help in stopping Oil leaks along the Stud Threads.
Needless to say it's been designed mainly for competition use on a dry sumped Engine.

looks very much like an HRE cam cover I saw on a an inject twin-cam, minus the HRE over the cams though....

You may be correct as the sump pan and fuel pump cover plate both have HRE cast into them which I believe is from Hutchinson Race Engines.

John,
The tab cast into the inlet side of the cover between cylinders 1 and 2 could have been use to mount a Lucas or Tecalmit mechanical fuel injection pump.

These cam covers were made by Hutchison Racing Engines. I emailed Gus Hutchison and he told me he made about 100 sets. A set consisted of the cam cover, cast dry sump with fins similar to the cam cover, a mechanical fuel pump blanking plate and a 4 port dry sump pump.

What are the chances of finding one of these? I have been happy with my original 1965 valve cover until I saw this-I really like the idea of the rigidity and the extra hold down studs-the original has too few.
